BUG: Preserve JPEG image quality by default

Fix #3515

Could we please rename pil_params to pil_parameters - or even pillow_parameters?

Additionally, in the best case all changes would have a corresponding test as well to avoid regressions and show that the changes to indeed have the desired effect.

OK, I will add some unit tests 👍

I think I fixed the final issues, and I added a unit test.

IMHO this is ready to be reviewed & merged.
